Flooring
Functionally, the banister is one of the main safety factors in a stairway and it’s parameters are called out in the local and national codes. Current California codes dictate that rail height must be between 34″ and 38″, measured plumb up from the stair nosing, and 42″ off of the finished flooring (formerly 36″) on a level balcony. Handrails must be graspable as determined again by codes as are the baluster spacing (less than 4″ spaces).

Framing
The structure of the Greene & Greene house is essential not only to the immense feeling of security that such an overly-supported structure brings, but also accentuates the importance of the Arts & Crafts fundamentals in the Greene & Greene style. The visual importance of the aesthetic nature of the joints, pegs, and complex wood-work symbolizes the structure of the house, and coincides with the principles taught in the Manual Training School of their youth. The structure of the house is externalized, or exploded, rather than hidden in decoration. Each element of the structure asserts itself. This extravagance of support takes its origins from the elaborate joinery and framing of traditional Japanese architecture.
Fireplaces
Medieval times as a hood that projected over a grate to catch the smoke. The term has evolved to include the decorative framework around the fireplace, and can include elaborate designs extending to the ceiling.
Staircases
Our team of experienced stair and handrail installers knows that a finely crafted stair embodies the highest art of the building industry and they take pride in proving their skills on every project. From small remodels to elaborate custom staircases, you can rest assured that every detail will be well thought out and finely attended to.

New Construction
Current handrail height standards (set by 2010 CA Building Code) is 34″ to 38″ on a stair and 42″ on a level balcony. The stair height is measured vertically from the step nosing to the top of the handrail. The 42″ level balcony is measured vertically from the finished flooring to the top of the handrail.Safety codes are always changing. The level balcony height was changed (2010) from 36″ to 42″. It is quite a change and continues to be an aesthetic as well as a logistic adjustment and the difference must be considered during the design stages of new construction or remodeling.

Decks
Cable balustrades have been designed for modern decks as well as modern stainless steel stairs but we have adapted the cable to work with modern interiors with the softer feel of our wooden posts.

Carpentry
Being a stair installer in the Sonoma, Napa, and Marin counties has been challenging over the years and after over 25 years in the business, I have built or remodeled thousands of staircases. During my apprenticeship there were many aspects of stair building that were different than any other woodworking that I had done (general carpentry, fabricating and installing cabinets). I was presented with a totally new set of challenges dealing with angles and radius's, rises, runs, codes, safety issues, etc. As daunting as all the layout and woodwork was, the chance to work on what I consider to be the focal point of a multilevel home, was and still is quite fulfilling. A stair builder needs to make sure that his product has structural integrity; a staircase is foremost a main artery of egress and safety is so much a factor, but also the staircase needs to have aesthetic appeal and it's appearance is a statement of design and architectural theme The following articles are meant to help those so inclined to become stair builders or those who simply want to build or remodel their own staircases. These articles will continue to be a work in progress. Hopefully they will be of enough help that the reader can go forward with a basic knowledge of stair building. Over the span of my career a lot of my acquired knowledge was hard earned and some of my most costly mistakes were the best lessons. Maybe these articles will help to prevent mistakes. My first mentor told me that if I understood the dynamics of one step, with it's run, rise and pitch, that I would understand the whole stair. He had a point, but typically the first and last step of a staircase are the ones that need special attention and all of the other middle steps usually just follow redundantly. Robert Bertram
